The evolution of citizenship: economic and institutional determinants

We investigate the evolution of the legal institution of citizenship from a political economy perspective. We first present a median voter model of citizenship laws determination. Next we test the implications of the model on a new data set on citizenship laws across countries of the world. We show that they have responded endogenously to economic and institutional determinants. Migration pushes national legislation in the direction of jus sanguinis. Moreover, the impact of migration interacts with that of the legal tradition. In particular, countries with a jus soli origin tend to restrict when facing an increase in immigration, while in jus sanguinis countries migration has a negligible impact. The welfare burden proves not to be an obstacle for a jus soli legislation, while demographic stagnation encourages it. A high degree of democracy promotes the adoption of jus soli elements, while the instability of state borders determined by decolonization impedes it. Religion and ethnic diversity have no residual impact

Family Planning and Ethnic Heritage: Evidence from Sub-Saharan Africa

Family planning is a critical issue in countries, particularly those in sub-Saharan Africa, where high fertility rates coexist with low contraceptive use alongside adverse perinatal outcomes. Using a combination of ethnographic, ecological, and folklore data, we investigate the role played in this context by postpartum sexual abstinence, an extensively documented practice that, in preindustrial societies, finds its biological justification as a means to safeguard child survival. First, we show that the duration of contemporary postpartum abstinence increases with the duration of ancestral postpartum sex taboos within a woman’s ethnic group. Second, postpartum abstinence is de facto pronatalist, as it increases the number of children ever born to a woman. At the same time, it increases the number of children of a woman who have died; lengthens birth intervals though not sufficiently to meet recommended guidelines; and increases neonatal death and child stunting. Exploring the underlying mechanisms reveals that postpartum abstinence is associated with patriarchal cultural norms and that the motivation for its adoption is that it serves as a purification ritual. Overall, our findings question the biological rationale for postpartum abstinence as a means to protect child health, while aligning with anthropological evidence documenting its adoption as a ritual

Is it money or brains? The determinants of intra-family decision power

We empirically study the determinants of intra-household decision power with respect to economic and financial choices using a direct measure provided in the 1989-2010 Bank of Italy Survey of Household Income and Wealth. Focusing on a sample of couples, we evaluate the effect of each spouse's characteristics, household characteristics, and background variables. We find that the probability that the wife is in charge is affected by household characteristics such as family size and total income and wealth, but more importantly that it increases with the difference between hers and her husband's characteristics in terms of age, education, and income. The main conclusion is that decision-making power over family economics is not only determined by strictly economic differences, as suggested by previous studies, but also by differences in human capital and experience. Finally, exploiting the time dimension of our dataset, we show that this pattern is increasing over time

Who holds the purse strings within the household? The determinants of intra-family decision making

We study the determinants of intra-household decision-making responsibility over economic and financial choices using a direct measure provided in the 1989–2010 Bank of Italy Survey of Household Income and Wealth. We find that the probability that the wife is responsible for decisions increases as the wife’s characteristics in terms of age, education and income become closer or even higher than those of her husband’s. Thus, consistently with a bargaining approach, decision-making responsibility is associated with marriage heterogamy, and not only along strictly economic dimensions. However, in support of an alternative household production approach, we also find that the probability that the wife is responsible is lower when she is employed, which suggests the presence of a specialization pattern assigning responsibility to the spouse with more available time. Our results are robust to additional controls and alternative samples

Bibliometric Evaluation vs. Informed Peer Review:Evidence from Italy

A relevant question for the organization of large scale research assessments is whether bibliometric evaluation and informed peer review where reviewers know where the work was published, yield similar results. It would suggest, for instance, that less costly bibliometric evaluation might - at least partly - replace informed peer review, or that bibliometric evaluation could reliably monitor research in between assessment exercises. We draw on our experience of evaluating Italian research in Economics, Business and Statistics, where almost 12,000 publications dated 2004-2010 were assessed. A random sample from the available population of journal articles shows that informed peer review and bibliometric analysis produce similar evaluations of the same set of papers. Whether because of independent convergence in assessment, or the influence of bibliometric information on the community of reviewers, the implication for the organization of these exercises is that these two approaches are substitutes
